Maintenance of  viability in storage  
        
          - 
            
Store well mature seeds 
           
          - 
            
Store normal coloured seeds  
           
          - 
            
Seeds should be free from mechanical injury  
           
          - 
            
Seeds should be free from storage fungi or micro  organisms 5. Seeds should not have met with adverse conditions during  maturation. Storage godown should be fumigated to control storage insects,  periodically  
           
          - 
            
Storage environment or godown should be dry and  cool.  
           
          - 
            
Seeds should be dried to optimum moisture  content  
           
          - 
            
Required R.H. and temperature should be  maintained during storage.  
           
          - 
            
Seeds should be treated with fungicides before  storage  
           
          - 
            
Suitable packaging materials should be used for  packing. 
           
         
        Factors influencing seed storage 
        
        1.Biotic  factors (Click here ) 
           
        a. Factors related to seed 
        
        
          
              - Genetic make up of seed
 
              - Initial seed quality
 
              - Provenance
 
              - Seed Moisture content
 
             
             b. Other biotics 
        
          
            - Insects
 
            - Fungi
 
            - Rodents
 
            - Mishandling during sampling, testing
